Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a display device suitable for use in a personal computer, word processor, or other picture-mixed document processing system, and particularly relates to a display device suitable for use in a personal computer, word processor, or other picture-mixed document processing system. When creating or editing a document, that is, a mixed-mode document, the operator can display the text area, image area, and the overlapped area in different background colors.

The present invention relates to a display device for a picture-mixed document processing system that improves the operability of creating and editing mixed-mode documents by making it possible to easily identify each area.

Conventional technology Image processing is possible in data processing systems controlled by microcomputers such as personal computers and word processors.

In addition to the keyboard, an image reading device such as a scanner is connected.

However, in the display device of the conventional picture document processing system, the display processing of the image portion is handled at a lower level than the display processing of the text portion.

For example, for an image portion, a frame is specified within the text portion, and image data is inserted into this frame. It is done in this way.

Therefore, when the text portion is modified, the text invades the image portion. Such cases often occur.

That is, with this method, it is not possible to determine how the text and image overlap, and in some cases, the text data may be hidden by the image data.

Furthermore, even if the image is determined to be a text portion based on the screen display and an attempt is made to modify the text, the text may actually be image data and cannot be modified.

In this way, with the display device of the conventional picture document processing system, especially when the image part and the text part overlap, it is not easy to determine from the display screen which data it is. Therefore, there is an inconvenience in that the operating efficiency when creating and editing mixed mode documents decreases.

Purpose Therefore, the display device of the picture-mixed document processing system of the present invention solves these inconveniences in conventional display devices, and allows the operator to easily control the text area and the image area, even when both areas overlap. The purpose is to improve operability by making it possible to easily identify each area from the screen display and reducing the burden when creating and editing mixed mode documents.

For this reason, the display device of the picture-mixed document processing system of the present invention includes an image data reading means, an input means for inputting data such as characters and control information, and text data forming a one-page document. The apparatus includes a color display means for displaying image data on one screen, an area setting means for setting a rectangular text area and an image area on the screen of the display means, and a central processing unit for controlling each of these parts. In a picture-middle document processing system having a picture-middle document creation/editing function, information on predetermined different background colors is added to the text area and the image area, respectively, and when creating/editing a picture-middle document, The set text area and image area are displayed in different background colors depending on the background color information, and a portion where the two areas overlap is displayed in a background color different from that of the text area and image area. It consists of

What are CPU II, ROM12, and RAML3?

The computer section includes a CPU I which controls the system shown in FIG. 1 that constitutes a personal computer, a ROM 12 which stores character pattern data, and a RAM 13 which constitutes a system memory.

In the display device of the picture mixed document processing system of this invention,
Created mixed mode Bun'an at the same time as W.

In the 1 page area DP on the screen of the CRT display 3,
Set a text area and an image area. however,
An area that does not fall into either of these areas.

The existence of an overlapping portion corresponding to both the text area and the image area is recognized.

Note that when creating a picture-like document, that is, a mixed mode document, using the word processor function of a personal computer, there are two methods for setting a text area and an image area.

The first method is to set a text area and an image area in advance.

The second method is to set the text area and the image area as the editing operation progresses without distinguishing between the text area and the image area at first. In this case, each area is
Set for the axis and Y-axis direction.

By the way, in the display device of the picture mixed document processing system of the present invention, display data representing one pixel in a 4-bit configuration is provided in the VRAM 4B, as described above.

One bit of the display data consists of 4 bits.

Indicates whether the pixel is displayed as a bright spot or a non-bright spot.

The other 3 bits of display data are color R and G.

For example, when displaying in red, R=1
．． G=O, B=O, and when displayed in green,
It is assumed that R=O, G=l, and B=O.

Similarly, when displaying in white, R=1. G=1°B=1
It is said that

For example, set the background color of the text area to white,
The background color of the image area is predetermined as green and the background color of the overlapping part as red, and the pattern itself of the text or image is displayed, for example, in black (non-bright spots).

Next, a description will be given of display processing when creating a document in mixed mode regarding the display device of the picture-mixed document processing system of the present invention.

FIG. 2 is an example of a screen display when creating a mixed mode document in the display device of the picture mixed document processing system of the present invention shown in FIG.

In the drawing, DP is one page area of the CRT screen, Po
is the reference point of the 1-page area DP, Pl and P3 are the reference points of the text area, Pl is the reference point of the image area, x, y are the coordinate positions of the reference points of each text area and image area, Xy
Y indicates the dimensions of each text area or image area.

Even in the case of a method in which the text area and image area are set in advance, or in a method in which the text area and image area are set as the editing operation progresses without distinguishing between the text area and the image area at first. Even in this case, a 1-ryo area is ultimately set.

No matter which setting method is used, the reference point P at the upper left corner of the text area or image area on the display screen in Figure 2.
The coordinate positions (X, Y) of 1 to P3 and the dimensions of each area (x,
y) is created as a text attribute separately from text information and image information.

For example, for the upper image area, the reference point P of the one page area DP. According to the distance x, y from to the reference point P1 of the text area, Pl (XI.

'y+) and the dimension of the area (x+ * y+),
Create as a text attribute.

The same applies to the image area below it.

Reference point P2 (X2, Y2) and the dimension of the area (x
2゜y2) is created separately as an attribute. In addition.

X2. Y2 is the reference point P of the one page area DP. The distance from the reference point P2 of the image area to the reference point P2 of the image area, X2+y2, indicates the size of the area.

The mixed mode document is displayed on the screen of the CRT display 3, as shown in FIG. 2, based on the text attributes created separately from the page information.

Therefore, in the above embodiment, for example, the background color of the text area is specified as white, the background color of the image area is green, and the background color of the overlapping area is specified as red. It is also assumed that text and images are displayed in black, for example.

Display processing using such display data is performed as follows.

Here, if the coordinates of the scanning position are (x, y), the text area of the reference point P is as follows:
l≦Y≦YI+3'I (2), and the image area of reference point P2 is: X2≦X≦X2 +x2 (3) Y
2 ≦Y:5Y2+)12 ・・・・・・(
4).

Therefore, equations (1) and (3) hold, and equation (
In the range where 2) and (4) hold, the surface areas overlap.

The separately created text attributes are "white" for the text area and "green" for the image area, but will be displayed in "red" in areas where the surface areas overlap.

On the other hand, only equations (1) and (2) hold true,
The range where Equations (3) and (4) do not hold is the text area; conversely, only Equations (3) and (4) hold and Equation 5 (1
) and (2) do not hold, it is determined that it is an image area, and based on the separately created text attribute, the former is
white”, the latter is filled in with “green”.

FIG. 3 is a flowchart showing the flow of display processing when creating a mixed mode document in the display device of the picture mixed document processing system of the present invention shown in FIG.

When displaying on the CRT display 3, as shown in the flowchart of FIG. 3, it is determined whether a text area or an image area is set.

If a text area has been set, it will be displayed with a "white" background color, but if the coordinate position corresponds to the text pattern, it will be displayed in "black".

Also, if the image area is set, it will be "green".
It will be displayed with the background color of "black" if the coordinate position corresponds to the pattern of the image.
It will be displayed.

On the other hand, areas where the text area and image area overlap will be displayed in a red background color, but if the coordinate position corresponds to a text or image pattern, the background color will be displayed in black. It will be displayed.

Such arithmetic processing is performed by the CP of a personal computer.
The calculation is performed by a computer section consisting of a UII, etc., and the calculation results are written and stored in the VRAM 4B, and each area is displayed in color under the control of the CRT controller 4A.

Therefore, from this color display, the operator can determine the area of the document that he or she wishes to edit.

It is possible to easily identify whether the data is text data or image data.

In other words, if the background color is red, that area is an overlapping area, so if you are currently using that area as a text area, you can Edit and also
If it is used as an image area, the image data will be edited.

As described above, in the display device of the picture-mixed document processing system of the present invention, the text area and the image area are displayed in color according to the text attributes created separately, and the overlapping part of the two areas is displayed in color according to the text attributes created separately. Display in a different color, separate from the attribute.

Therefore, it is possible to create and edit a mixed mode document accurately and easily without misunderstanding the area to be edited as in the past, and the operating efficiency is improved.

Note that in the above embodiments, the case of a personal computer has been described. However, it is applicable to display devices used in picture-mixed document processing systems such as G4 facsimile, teletex, LAN, and mixed-mode word processors, and the display of the picture-mixed document processing system of the present invention is applicable. The device is not limited to the personal computer of the embodiment.

As described above in detail, the display device of the picture-mixed document processing system of the present invention includes an image data reading means, an input means for inputting data such as characters and control information, and text data forming a one-page document. color display means for displaying and image data on one screen; area setting means for setting rectangular text areas and image areas on both sides of the display means; and a central processing unit for controlling each of these parts. In a picture-middle document processing system having a picture-middle document creation/editing function, information on predetermined different background colors is added to the text area and the image area, respectively, and when creating/editing a picture-middle document, , the set text area and image area,
The display is configured to be displayed in different background colors depending on the background color information, and a portion where the two areas overlap is displayed in a background color different from that of the text area and the image area.

Therefore, according to the display device of the picture-mixed document processing system of the present invention, the operation target area of the document to be edited is
Since each area is displayed in a different color, it is possible to easily and accurately identify whether the area is text data or image data.

As a result, it is possible to prevent misidentification of the operation target area as in conventional display devices, and to achieve the excellent effect that the operability of the system is significantly improved.
